I am currently 5th in a 10 team mixed keeper league with 7 keepers per team. It is scored head to head categories and the categories are for offense: runs, avg, ops, hr, rbi, and sb and for pitching: w, qs, k, sv, era, and whip. My team is as follows:

Your early lineup speed guys have been underperforming. Don't be afraid to bench someone if they aren't cutting it. Your power guys are real good. Melky would be the perfect type player to trade for. Austin Jackson also would be a good addition for you and would be a lot easier to get than Melk. Check to see if Ben revere is on you WW. HIs runs/ave should stay pretty good.

Upside is weeks has been picking it up and really just one good speed guy will make a big diff. Good luck.
